Analog Front End Eyes DSL Systems

Optimized for DSL communication systems, such as HDSL and SDSL, the AFE1144 analog front end provides all the circuitry required for connecting a DSP to a line transformer. The device consists of a transmit and receive section. The transmit section generates and filters analog signals to create 2B1Q symbols. The receive portion filters and digitizes the symbol data received on the telephone line and an on-board differential line driver provides a 13.5-dBm signal to the telephone line. Other features include PSD-compatibility, a scalable data rate from 64 kb/s to 1168 kb/s, a serial digital interface, a power dissipation spec of 250 mW, and operation from a single 5V supply. Pricing is $9 each/1000 with delivery from stock.
